DAVID s. JACoBUs, or nonrctarn, new JERSEY, AND wILtrAM A. Jones, orVwrist" NEW BRIGHTON, NEW YORK, ASSIGNORS TO THE BABCOCK AND-WILCOXCOMPANY, OF BAYONNE, NEW JERSEY, A CORPORATION OF NEW JERSEY Y i SOOTPOCKET FOR BOILERS Applivasion med oct'ber 12, 1925,"sei-iai No. 62,063.Renewed N byember 22, V193e. i

This invention relatesto aV soot pocket `in-f Y stalled to catch sootland dust that are separated from the gases 'in owing through thesettings in `waterltube boilers, and will be understood from thedescription in connection Withthe accompanying drawingsuin which Fig. 1is a longitudinal section through a Babcockt Wilcox type of boilershowing where the soot pocket 1s placed;

Fig. 2 is a vertical section of an enlarged detail; Fig. 3is a sectionalong the line 3 3 of Fig.2,-and Figs. 4 and-5 are plan views' ofdetails. i v

In the drawings, reference character 1n- 4dicates a furnace or-.ire box,in the front ers 15 and 16, the header 16 being connected to a mud drum17 at itsY lower side, and theY headers and 16 being connected to asteam and water drum 18 in the usual manner. Af superheater 19 is shownlocated between the upper bank 14 of tubes and the steam and water drum18.

A longitudinal baiiie 2O rests upon a row of tubes in the bank 14, and atransverse baffle 21 extends from near the upper end of the baiiie 20across the banks of tubes 14 and 14. A transverse baiiie 22 also extendsacross the bank of tubes 14, and is located between the baiiie 21 andthe header 1G. A. vertical bale formed of tile 23 and flame plates 24(Fig. 2) faced with tile, extends from the upper edge of the wall 12 tothe lower end Vof the baiiie 20. rThis baiiie rests upon luting material25 on the upper edge of the wall 12, this luting material beingcompressible and serving to fill the space to avoid the collection ofsoot and dust between the top of the wall and the bottom of the baffle.

rwi du in the tile in the well-known manner. The

members-29 vare provided `with hooksV 31 which project through slits inthe'metal plate 32 which serves to keep the part 27 of theV forced withvertically extending channels 33. The bottom 34 of the soot box may belconnected by angle irons 35 to the sides .32

and 36 ofthe box, and thev` box is provided on one side near` its lowerend with the door 37. The side 36 of the soot box `maybecon-v nected bymeans `of U-bolts 38 tothe nipples` .Y which connect the header 16 tothemud'drum 17, there being a sliding joint betweenvthe side 36 and themud drum' 17 to allowfor expansion. Angle braces 39, are placed in thesoot box to holdA the plate 32 in vertical alignment, the entireconstruction being also braced by means of the channel iron 40.*

The burners 11 are mountedina metal plate 41 v(Fig 1), upon the upperedge-of which the soot box rests, and a channel iron 42 may be usedforsupporting the plate 41.

' A spacer 45 Fig. 5) is usedto'prevent the baiiie 23 from sliding alongthe tubes 14, as most clearlyshown in Fig. 2.` The long portions of thespacer 45 are provided` with rounded sides to rest upon the tubes 14,and

Vthese long portions are vjoined by cross Vthe upper edge of wall 12 andthe lower end of baffle 20 comprises'tile 23, as shown in 4 withrabbeted edges as shown at 23 and 23,

so that these edges will fittogetherwhenthe tile areVV assembled lin astraight wall. The lower edge of the lowest .tile 23 forms asliding`joint with the offset portion 48 of the plate 32,A thus permittingVrelative movement in a vertical plane. The side V36 ofthe soot box maybe provided with holes elongated in a vertical direction, through whichthe]U 190 bolts 38 pass, thus permitting the header 16 to movevertically in relation to the wall 36, due to expansion and contraction.

We claim: j 1. In combination, a water tube boiler having inclined tubesconnected to a header at one end, a furnace having a wall spacedinwardly from' said header, whereby a length sliding connectiontherewith.

3. In a water tube boiler, inclined tubes connected to headers, meansproviding gas passes across said tubes, a metallic soot pocket locatedbeneath the lower ends of said tubes, said soot pocket beingsubstantially air-tight, and a sliding joint between said soot pocketand boiler parts.v

4. In a water tube boiler, inclined tubes connected to headers, meanslproviding gas passes across said tubes, a soot pocket located beneaththe lower ends of said tubes, and sliding means to permit relativemovement between each side of said Ysoot pocket and boiler parts.

5. In a water tube boiler, inclined tubes connected to headers, meansproviding gas passes across said tubes, a soot pocket located beneaththe lower ends of said tubes, and means comprising asubstantiallyair-tight sliding joint to permit relative movement between said sootpocket and boiler.v

6. In a water tube boiler, inclined tubes connected to headers, a muddrum beneath one of said headers, means providing gas passes acrossVsaid tubes, anda soot pocket located beneath the lower ends of 'saidtubes in promiXity to said mud drum and having Ya sliding connectionwith said drum.

7 In awater tube boiler, inclined tubes having a header connectedthereto at one end, ,a furnace wall spaced inwardly from said portion ofsaid'wall and boiler parts.

8. In a water tube boiler, inclined tubes connected to headers, a muddrum beneath one of said headers, means providing gas Y passes acrosssaid tubes, and a soot pocket located beneath the lower ends ofsaidtubes in proximity to said mud drum with its outer n wall substantiallyin alignment with the inner wall of said mud drum and having a slidingconnection therewith.

9. In a water tube boiler, inclined tubes i llower ends thereof, a sootpocket below said tubes at the rear of said wall, a bale eX- tendingacross some of said tubes, a sliding Y joint between one side ofy saidsoot pocket and said baiile,rand a sliding joint between the other sideof said soot'poclret and said header.

l0. In a water tube boiler, inclined tubes connected to headers, a wallbelow said tubes near the lower ends thereof, a soot pocket below saidtubes at the rear of said wall, a baffle extending across some of saidtubes, near one side of said pocket, andvmeans between said baiile andheaders to prevent said baille from sliding downwardly along said tubes.-A

1l. In a water tube boiler, inclined tubes,

each having one end thereof connected to a.v

ing joint between one side of said soot pocket.
